Document Summary
Tailpipes and global )arming: overview, the atmosphere. Insulation makes earth habitable for life i: the carbon cycle, plants absorb sunlight, and absorb water/carbon dioxide from atmosphere, and form a sugar (cid:840)glucose(cid:841) i. Ir energy (cid:840)heat(cid:841) does not pass back out the glass; it is trapped. The black floor = earth"s surface: think of your car"s black upholstery in the summertime, greenhouse effect is a natural process that traps the heat from light during night/day in the winter/summer. Central atom : co 2 , water vapor, o one, nitrous oxide, methane, freons, nox, sox, . Diatomic (cid:840)99%(cid:841: most atmospheric gases are . Ex. nitrogen/oxygen: carbon dioxide and air pollution i. Not a new phenomenon: air pollution is , as early as , further deadly episodes occurred in 1911, 1952, 1956, 1957, and 1962, triatomic gases contribute to global warming/greenhouse effect. Londoners died of smog : some gases contribute more than others.
